P2C6E: Drive Motor "A" Phase Y Current High

Phase Y current of drive motor A exceeds the expected window. Indicates phase short, stalled rotor, or sensor offset.

Symptoms

• EV/hybrid system warning light on
• Reduced motor power or torque
• Possible limp mode or vehicle shutdown

Most likely causes

• Short between motor phases
• Rotor stalled - high stall current

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
3. Make sure the battery cooling air intake is clean
4. Check the 12 V auxiliary battery, which can also trigger warnings
5. Leave any high-voltage measurements to a specialized repair shop

Good to know

• Repair difficulty: hard
• It can trigger limp mode.

What each character of P2C6E means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• C: Subsystem depends on the code range
• 6E: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2C6E?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P2C6E?

The most common causes are: short between motor phases; rotor stalled - high stall current.
